Lead Carbonate - Render

Lead carbonate stains, often seen as white or grey streaks or patches, form when lead components—such as those in nearby fixtures, pipes, or roofing—react with oxygen and moisture over time. This staining can be particularly stubborn on render surfaces, as it often penetrates deeply and causes noticeable discolouration that detracts from the render’s appearance. PureSeal’s lead carbonate removers are specifically formulated to break down and lift these challenging residues without impacting the texture or colour of the render.

Our lead carbonate removers directly target the deposits, dissolving the buildup to restore the render’s original clean look. For best results, follow product instructions carefully, perform a test patch to confirm compatibility, and use appropriate PPE to ensure safe handling.
